WILLIAM SCIIUTTLEE, 01 CHICAGO, ILLINOIS,

ASSIGNOB TO UNIVERSAL ARCH COM- LOCOMOTIVE ARCH.

Application filed November 20, 1922. Serial No. 602,016.

To all whom it may concern:

Be it known that I, VVILLIAM sCHUTTLER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Locomotive Arch, of which the following is a specification.

My invention relates to locomotive arches and particularly to a novel form ofbrick construction adapted for use in forming the transverse balile or wall interposed in a locomotive fire box for the purpose of deflecting the products of combustion. A detail of the construction herein disclosed was first illustrated in my Patent No. 1,420,761, of June 27, 1922. 1

One of the objects of my invention is to provide a construction in which the inclined side bricks shall be so supported that no transverse bending strain shall be exerted on the side tubes. In the use of arches including an inclined side brick it is not unusual for the side bricks to be installed at such an angle that the continued jar and hannner- .ing, due to the passing of the engine over joints, causes the side bricks to wedge in the space between the outside tube and the side sheet and to bend the tube. In the construction here proposed this difliculty is obviated. The side bricks are supported directly on one of the horizontal bricks and the thrust is distributed over all the tubes. By providing on each end of the horizontal bricks and on the larger end of the side brick a hemispherical recess and protuberance, the bricks are made interchangeable and are suitably interlocked without weakening the bricks. This form oi interlock has another advantage in that it is so aranged that the workman cannot place or rest the side brick on the outside tube but must place it in its proper position in engagement with the horizontal brick.

The invention will be more readily understood by reference to the accompanying drawings, in which,-

Fig. 1 is an end view of a common form of arch constructed in accordance with my invention Fig. 2 is a similar view showing a slightly modified form;

Fig. 3 is a top plan view of one of the horlzontal bricks, and

Fig. 1 is a bottom plan view of a side brick.

In the drawings, referring particularly to Figs. 1, 3 and 4., it will be seen that the improvement is shown as applied to a fire box having side sheets 10, and four arch tubes 11. On the tubes are placed bricks 12, the ends of the bricks being grooved to fit on the tubes and the lower surfaces being recessed as indicated at 13. On each end of the middle bricks 12, I provide a hemispherical projection or protuberance 1 1, and a hemispherical recess 15. These are staggered on opposite ends as indicated in Fig. 1, the brick thus being reversible.

The side bricks 16 are of thinner construction and may likewise be provided with recesses 17 on their lower surfaces. The outer ends 18 are shaped to fit the side sheets 10, and the inner end 19 rests against the inclined portion 20 of the horizontal brick. The end 19 of the side brick is not exactly square but is slightly curved, as shown, in order to permit certain freedom of movement of the side brick to correspond to necessary variations in the space between the side sheet and the outer tube.

In the construction shown in Fig. 2, the bricks 12 and 16 are the same as those just described. However, in this instance the intermediate tubes 21 are more widely spaced and twobricks 22, 23, are e111- ployed for bridging the space, these bricks being each of arcuate form and when joined constitute a fiat arch. The abutting ends of the two bricks are similarly provided with a hemispherical recess and projection. To this extentthe construction is similar to that shown in my patent heretofore referred to. However, in that patent the ends of the bricks are rested on the tubes, whereas in this case the bricks are rested on the ends of adjacent bricks.

It will be noted that the middle bricks 12 are of arcuate form. This construction provides several advantages, one of the most important of which is that of stability even though the brick may be broken trans transversely. The arched shape of the brick will insure the maintenance of the brick in position even under the circumstances men tioned, f

A construction such as described adapts itself toall the requirements or" removal and replacement and may be cheaply manufactured. The form of the'interlocking device is such that the bricks may be handled 'Wltlt out danger of breaking off the projections. Obviously the construction is capable of adaptations other than those shown and I do not Wish to be limited except as indicated in the appended claims.

I claim:

1. The combination ,With the side sheets and tubes of a locomotive, of bailiewall comprising middle bricks and side bricks, the middle I bricks supported on, and fitting between the tubes and the side [bricks v leaning against'the side sheet and supported on the end of a middle brick, the cooperating surfacesof the side' and middle bricks be.- ing provided with cooperating hemispherical recesses and projections, the ends of said themiddle bricks supported on and fitting between the tubes and the side bricks leanmg against the side sheet and supported on the end of a middle brick, the cooperating surfaces of the side and middle bricks being provided With cooperating hemispherical recesses and projections, one of said cooperating surfaces being rounded to permit or limited freedom oi movement of the side bricks to accommodate itself to the side sheet, said middle bricks being of arcuate form and having recesses on their under surfaces to lessen the Weight thereof.
